Description

CONTROL DEVICE WITH INDEXING MEANS THE POSITION OF CONTROL MEANS

TECHNICAL FIELD OF INVENTION

[0001] The invention relates to a control device comprising a manual control member connected to control means for sending commands, control, and comprising first means for indexing the position of said manual control member .

STATE OF THE ART

[0002] The use of control devices having a manual control member is widely used in particular for aeronautical applications, such as control handles of airplanes or helicopters.

We also observe -designed control device in the automobile, computer or handling or lifting applications.

[0003] Many patents disclose control devices where a control lever .comporte one or more degree of freedom. Tilting or rotation of the lever allows in particular to send a control command.

[0004] The control devices may generally include one or more sensing means of the movements of the control lever. The detection means comprise in particular Hall-effect sensors associated with permanent magnets or inductive windings based systems.

[0005] Furthermore, the control devices may also include means for indexing the position of the control means. The indexing means allow the user to have a tactile rendering of the position of the control lever. The indexing means are particularly associated with the rotational movement of the control lever. [0006] Existing solutions as presented in the patents FR2392479, FR2495373 use one or more mobile divers working with notches placed in a body. One can also observe the ball / spring sets. These solutions include the disadvantage of being noisy considering the movement of the plunger against the notches. The patent application FR2654898 proposes a quieter solution than previous but requires the presence of additional parts.

[0007] Generally, these mechanical solutions have reduced stamina for moving parts can break especially after a number of uses or cyclic stresses. In addition, the presence of contact between various mechanical parts introduces friction that may affect the movement of the control levers.

[0008] The solutions of the patent applications FR2804240, FR1167718 and US3458840 describe the use of two multi-polar magnetic concentric crowns. When the user turns the button or control lever, the magnetic poles of the inner and outer ring are placed opposite. The tactile effect that the user feels is close to that which would be obtained by notches or cams. The repulsion and / or attraction of magnetic poles facing are causing the touch effect.

[0009] The magnetic poles of the crowns of FR2804240 documents FR1167718 are made of sintered magnetic material. The crowns are magnetized to alternately form north poles and south poles at facing surfaces. The magnetic ring disclosed in US3458840 comprises a circular body on which is fixed a number of magnets. Given the relative complexity of crowns and whatever the solution chosen for their embodiment, the manufacture of the relatively complex and expensive.

[0010] The solution US6182370 discloses a control device with magnetic indexing means provided with a permanent magnet whose poles are arranged in the axial direction. When this type of indexing means is concomitantly used with detection means of the position of the control device, the permanent magnet can not be used for the detection of the rotary movement. Additional resources must be added.

[0011] The solution FR2698720 describes a variety of magnetic indexing principles that do not allow analog detection of a rotary movement, let alone combined with the translation of detection along the same axis.

[0012] Finally, the current means can have a significant footprint.

DISCLOSURE OF INVENTION

[0013] The invention therefore aims to remedy the disadvantages of the prior art, so as to provide a control device comprising indexing means.

[0014] The control device according to the invention comprises first indexing means comprising at least one magnetized magnetic element comprising at least one magnetic pole having a periphery cut according to a first notched profile, and comprising a ferromagnetic indexing support comprising at least a second notched profile. Said respective notched profiles of the magnetized magnetic element and of the indexing support are intended to be placed opposite so that magnetic flux flowing between said magnetized magnetic element and said indexing support varies over moving the manual control means.

[0015] Advantageously, the magnetic flux varies between two values, a maximum value where at least one notch of the magnetized magnetic element is positioned facing with at least one notch of the indexing support and a minimum value where at least a notch of the magnetized magnetic element is positioned facing with at least one recess of the indexing support. W

[0016] Preferably, each magnetic pole of the magnetized magnetic element has a periphery cut along a notched profile, said notched profiles of the magnetic poles being intended to be placed respectively facing with at least one notched profile of the support of ferromagnetic indexing.

[0022] According to a development of the invention, the magnetized magnetic element guided in translation, is to be attracted by a ferromagnetic region of a cup, the translation of the manual control means causing one of said magnetized magnetic element.

[0023] Advantageously, the elastic means exert a repulsive force against the attraction of the magnetic member magnetized by a ferromagnetic region of the cup.

[0024] In a particular embodiment, the control means comprise first detection means of magnetic field variations of the magnetized magnetic element.

DETAILED DESCRIPTION OF AN EMBODIMENT

[0037] The control device 1 includes a manual control member 2 to be maneuvered by a user.

[0038] In a first preferred embodiment of the invention as shown in Figure 1, this manual control member 2 is intended to be connected directly to the control of mechanical means such as a gear 4 ei / or screw not shown end.

[0039] The control device 1 comprises first means for indexing the movement of the manual control member 2 in an XY plane. These indexing means allow the user to feel a tactile effect in each indexing position associated with sending a command.

[0040] As shown in Figure 1, the indexing means 3 comprise at least a first magnetized magnetic element 6. At least one of the magnetic poles (N, S) of said magnetized magnetic member has a cut edge according to a first notched profile . The indexing means 3 also comprise at least one ferromagnetic 7 indexing carrier having a second portion having a notched profile. Said respective notched profiles of the magnetized magnetic element 6 and of the indexing support 7 are substantially identical to cooperate during the movement of the manual control member 2.

[0041] In at least one position of the manual control member 2, at least one of the notches 6A of the magnetized magnetic member 6 is located respectively facing with a notch 7A of the indexing support 7. The flow magnetic the magnetized magnetic element 6 can then flow to the indexing support 7 via at least one pair of notches 6A, 7A.

[0042] The notches 6A, 7A of the magnetized magnetic element 6 and of the indexing support 7 are however not in direct contact. It is observed a gap between the teeth 7a of the indexing support 7 and the teeth 6A of the magnetized magnetic member 6. This gap serves firstly to avoid any friction during the movements of the magnetized magnetic element 6 and indexing support 7 and, secondly, allows the flow of magnetic flux of the first magnetized magnetic element to the indexing support.

[0043] In this embodiment, the magnetized magnetic element 6 is bonded to the manual control member 2. Thus the rotation of the manual control member 2 as a Z-axis causes rotation of the magnetic poles N, S of the magnetized magnetic element 6 about the same axis Z.

[0044] According to one embodiment, each magnetic pole N or S of the magnetized magnetic member 6 comprises a cut edge according to the same notched profile. Said notched profiles of the magnetic poles N, S are intended to cooperate respectively with said at least one notched profile of the ferromagnetic indexing support -7. In the exemplary embodiment, taking into account the rotation of the magnetic poles N, S of the magnetized magnetic element 6 about the axis Z, the indexing support 7 comprises a circular toothed profile disposed on a ring. The magnetized magnetic element 6 is placed inside said ring of which the notches are disposed on an inner periphery. It is thus observed a periodic distribution of notches 7a on the inner profile of the crown 7. The longitudinal axis of crown 7 is substantially coincident with the axis of rotation Z of the magnetized magnetic element 6. This periodical distribution of notches in the fastener indexing is substantially identical to the periodic distribution of notches 6A observed for the magnetic poles of the magnetized magnetic element 6.

[0045] When the teeth 6A of the magnetic poles of the magnetized magnetic element 6 are placed facing with notches 7A of the indexing support, the indexing means 3 are in a stable state. A maximum magnetic flux circulates between said one magnetized magnetic member and said indexing support .. The magnetized magnetic member 6 and the indexing support 7 are held one-by to each other by a magnetic force of attraction which is then maximum.

[0046] According to this configuration where the indexing support comprises a ring having a notched profile, loops of magnetic field of said magnetized magnetic element can be closed via the notches 6A North magnetic pole of the first working notches 7A of the indexing support 7, the teeth 6A of the south magnetic pole cooperating second detent 7A of the indexing support 7 and the ferromagnetic structure of the indexing support 7.

[0047] As soon as a displacement of the magnetized magnetic element 6 is observed, the notches 6A V 7A of said magnetized magnetic element and substrate will be completely screw in screws. There is a gap between said notches.

[0048] In a first part of the movement, the magnetic flux between the magnetized magnetic member 6 and the indexing support 7 tends to decrease to a minimum value when the teeth 6A of the magnetized magnetic member 6 are respectively screw screw with a recess in the toothed profile of the indexing support 7: in this first part of the movement, the magnetic system seeking to maximize the magnetic flux between the magnetized magnetic member 6 and the indexing support 7, a restoring torque around the Z axis tends to oppose the displacement.

[0049] In a second part of the movement, the magnetic flux between the magnetized magnetic member 6 and the indexing support 7 tends to increase, reaching a maximum value when all the teeth 6A of said magnetized magnetic member. found facing with a notch 7a of the notched profile of said indexing support. In this second part of the movement, the magnetic system seeking to maximize the magnetic flux between the magnetized magnetic member 6 and the indexing support 7, a return torque about the axis Z tends to favor displacement. [0050] Thus, in the first part of the movement, the user feels an opposition to his action and suddenly this opposition continues and turns into a travel assistance. This tactile effect can be felt especially each time a notch of the magnetized magnetic element 6 facing a notch of the indexing support 7.

[0051] The number of notches 7a and the arrangement of said notches on the indexing support 7 determine the number of indexing steps and therefore the number of tactile effects felt by the user by rotating the manual control member 2 along the axis Z.

[0052] A tire for example, the magnetized magnetic member 6 comprises a permanent magnet which is reported two magnetic parts. Magnetic pieces placed respectively on each of the poles of the magnet then comprise a notched profile. Other embodiments may be envisaged for the embodiment of the magnetized magnetic element 6. In fact, said magnetic element may especially comprise a permanent magnet whose poles are shaped as a notched profile such as described previously.

[0053] According to a second preferential embodiment of the invention as shown in Figure 2, the manual control member 2 may be connected to electrical control means 5. The electrical control means 5 comprise first detection means 8 for detecting the movement of the manual control member 2 in at least one direction. These detection means 5 are connected to non-represented processing means can send a particular control command.

[0054] As shown in FIG 2, first detecting means 8 of the movement of the magnetized magnetic element 6 are positioned in proximity to said magnetized magnetic element. In the exemplary embodiment, the first detecting means 8 comprises a magnetic sensor placed substantially on the axis of rotation Z of the magnetized magnetic element 6 at a distance H. In practice, the first detection means 8 are positioned on a first surface 9A of a shielding cup 9. the cup 9, preferably cylindrical, has a longitudinal axis substantially coincident with the longitudinal axis of the control member 2.

[0055] In this embodiment, the manual control member 2 does not cause the shield cup 9 to rotate about the Z axis, the latter being linked to the indexing support 7.

[0056] In this arrangement, the fixed magnetic sensor of the first detecting means 8 detects the variations in magnetic field 11 of the permanent magnetized magnetic element 6 in rotation about the longitudinal axis Z. Thus, the first detecting means 8 are capable to provide location information of the manual control member 2 in rotation about the axis Z. A positioning information may in particular be associated with each step indexed.

[0057] Furthermore, as shown in Figure 3, said first detection means can also detect the translational movement of the manual control member 2 along the axis Z. The first detecting means then detect changes 11 the magnetic field of the magnetized magnetic member 6 in translation along the longitudinal axis Z. Under the action of a manual actuating force FA, the manual control member 2 is movable over a distance Z1.

[0058] Elastic means 20 keep aside the magnetized magnetic element 6 of the first detection means 8 by exerting a repulsive force. The repulsive force tends to oppose the action of a manual force FA actuation. To move the manual control member 2, the AF operating manual force is greater than the repulsion force of the elastic means 20. Under the action of the manual force FA actuation, the distance H tends to be reduced and 11 the magnetic field measured by the first detecting means 8 varies. This magnetic field variation is interpreted by non-represented processing means.

[0059] In addition, during the movement of the magnetized magnetic member 6 in the direction of the first detection means 8 according to axis Z, said magnetized magnetic member is attracted by a ferromagnetic region positioned on the first side 9a of the cup 9. the magnetic force of attraction between the magnetized magnetic member 6 and the ferromagnetic region of the shield cup 9 increases faster than Ia repulsion force of the elastic means 20. Thus, beyond a certain displacement in the Z axis, the magnetized magnetic element suddenly be stuck to the ferromagnetic region of the cup 9. the user then feels a tactile perception known as failover. The magnetized magnetic member 6 and the ferromagnetic area cup 9 then form second means for indexing the movement of the manual control member 2 along the axis Z. The second indexing means comprise a single indexing steps .

[0060] Thus, at each validation of a control command sent by applying an actuating force FA on the manual control member 2, the user feels, in said direction Z control, a tactile effect.

[0061] During the rotation or the translation of the manual control member 2, the longitudinal axis of the manual control member 2 remains coincident with the axis Z.

[0062] The magnet 6 permanent magnetic element thus three distinct functions. First, it forms part of the first indexing means 3 for rotation of the manual control member about the axis Z. Second, it forms part of the first detecting means 8. Thirdly, i! is an integral part of the second indexing means of the translation of the manual control member 2 along the axis Z.

[0063] According to a third preferred embodiment of the invention, the manual control member 2 has a first end connected to the housing 10 by a ball joint and has a second end adapted to rotate relative to the first end moving according to at least one control direction. The alignment of the two ends defining a longitudinal axis of the manual control member 2. [0064] The control device 1 comprises second detection means 16 solid angular displacement α of the longitudinal axis of the guide member control 2 relative to the axis Z. in other words, the second detecting means 16 for detecting the displacement of the second end of the manual control member in a direction of the XY plane. As shown in Figure 5, the longitudinal axis of the manual control member 2 can indeed rotate around the Z axis after performing an angular displacement α.

[0065] The second detection means 16 composed of at least one magnetic sensor are used to measure changes in a magnetic field 22 produced by a second magnetized magnetic element 12.

[0066] According to this embodiment, the second magnetized magnetic member 12 is fixed to the housing 10 of the control device 1 and is stationary relative to the manual control member 2. The magnetic sensor of the second detecting means 16 is 9B positioned on a second face of the shield cup 9. the angular displacement of the longitudinal axis of the manual control member 2 with respect to the Z axis, causes the angular displacement of the shielding cup 9. the sensor magnetic 16 is then movable relative to the magnetized magnetic element 12.

[0067] According to another embodiment, the magnetic sensor may be fixed and the movable magnetized magnetic element. The magnetic sensor would be connected to the housing 10 while magnetized magnetic Péiément 12 would move with the manual control member 2.

[0068] Considering the respective positioning of the two magnetized magnetic elements 6, 12 on the faces of the shield cup 9, there is no magnetic interaction between the magnetic fields 11, 22 produced by the two magnetized magnetic elements 6, 12. This shielding washer 9 thus delimits two independent magnetic zones. The magnetic sensor of the first detecting means 8 does not detect magnetic field variations 22 of the second magnetized magnetic element 12 and conversely the magnetic sensor of the second detecting means 16 does not detect magnetic field variations 11 of the first magnetized magnetic element 6 .

[0069] When the control device is not used, a not shown return spring aligns the longitudinal axis of the manual control member 2 with the axis Z.

[0070] According to an alternative embodiment, the control device 1 comprises a connecting plate 90 connected to the control lever 2 via a sliding swivel connection. The connecting plate 90 has a first bearing face 91 in contact with a bearing zone of the control lever 2. The connecting plate 90 has a second bearing surface 92 in contact with the housing 10 by means of elastic holding means 100. According to this embodiment of the invention, the connecting plate 90 takes the form of a disc.

[0071] The elastic holding means 100 preferably consist of an elastic washer. This washer has a first radial face bearing against the housing 10. This washer comprises a second side supported on the second bearing face 92 of the connecting plate 90. The elastic means 100 then exert a retention force tending to maintain in contact the first bearing face 91 of the connecting plate 90 against the control lever 2.

[0072] The first bearing face 91 comprises at least two contact rails 93, 95. In this embodiment, said ramps are composed of planar portions having a flat ring shape respectively. An inflection point is observed between the second ramp 95 and the first ramp 93. In addition, according to this embodiment, the rings are concentric.

[0073] The bearing zone of the control lever 2 includes at least one projection 21 in contact with at least one of the ramps of the first bearing face 91.

[0074] The operation of the control device is as follows. When the control lever 2 is at rest, as shown in Figure 7, the holding force exerted by the elastic means .100 maintains said at least one projection 21 in contact with the first contact ramp 93.

[0075] When the control lever 2 is operated in one of the control directions, movement of said lever causes movement of said at least one protrusion 21 on the ramps of the first bearing face of the connecting plate 90.

[0076] According to the particular embodiment as shown in Figure 8, the movement of the protrusion on the first ramp 93 tends to increase the holding force of the elastic means 100. When the protrusion moves from the first ramp 93 in the second ramp 95, the elastic holding means 100 relax abruptly and the holding force decreases. The user then feels a tactile perception at the control lever 2. This tactile perception is caused by the passage of the protuberance at the inflection point between the two ramps. Indeed, at the time of said crossing, the holding force decreases abruptly increased.

[0077] The inclination angle between the first ramp and the second ramp determines the importance of the tactile perception perceived at the time of actuation of the control lever. In addition, the tilt angle value determines the importance of the gradient of the holding force at the time of transition from the first ramp 93 to the second ramp 95. The holding force depends in particular on the spring rate of elastic means 100.

[0078] According to another embodiment, the first bearing face 91 has at least three ramps of distinct touch.

[0079] According to another alternative embodiment of the invention embodiments, the contact ramps 93, 95 may have curved profiles taking a portion of circle, ellipse or parabola. The holding force of the elastic holding means 100 then varies according to the curve of said ramps.
